A debt is a debt. Beijing. Ministry of the General Administration of Civil Aviation. The aeronautical division of Group W, represented by André Bellecourt, is about to conclude a joint venture with the Tsai Industries. This alliance would allow the division, in difficulty for several years, to fear more serenely its future. But there is still a whim of Mr. Tsai Huang to satisfy to confirm the agreement: invite Largo Winch in person to sign the documents. The hiccup is that Largo is unreachable. Our hero has temporarily discharged from his obligations and lives cut off from the world in a secret place. Only Simon knows how to contact him. Dwight Cochrane the sum to warn his boss that the future of the group is at stake and that it is imperative that he be in Hong Kong in less than ten days. Largo will accept to return to China, even where a few years earlier he has experienced the worst debunks? An old debt contracted in Burma and that remembers his bad memory.
